Harrison will play Scott, who devises the desperate scheme when his terminally ill neighbour asks for his help to die and his brother Joey (Ben Heathcote) is in desperate need of cash to pay off his gambling debts.

Marc Wootton (Nativity 2: Danger in the Manger) will also star as Scott and Joey's friend Cozzo, with Laura Aikman (Casualty), Sinéad Matthews (Ideal) and Hannah Job (Coming of Age) rounding out the regular cast.

Zai Bennett, controller of BBC Three, said: "Bob Kushell's scripts are in turn dark, poignant, absurd, moving and brilliant. But mostly they are very, very funny. I'm thrilled that Way to Go is coming to BBC Three."

Writer Kushell added: "As someone who was weaned on great British comedy, including Monty Python, Blackadder and Fawlty Towers, there has been no bigger thrill in my life than to have a show on the BBC (narrowly edging out the birth of my son and trouncing my wedding day by a landslide). In over 20 years of writing comedy, I've never worked with a better cast and crew."
